Abstract

Stroke contrast is preserved for a range of font sizes and display resolutions using programmatic constraints or "hints". One implementation of a "font hinting" approach enforces a regularization of stroke weights such that stroke contrast is preserved for font sizes and display resolutions sufficient to render it. Font hinting instructions determine a stroke contrast threshold, which may be used to decide whether to preserve or omit stroke contrast when rendering the glyph. In one implementation, the stroke contrast threshold is based on one or more stroke contrast relationships associated with the typeface. In other implementations, the stroke contrast threshold is based on a minimum size threshold or lowercase/uppercase stroke contrast relationships.
